Hi Im 100% certain its that sponge gasket around the LCD panel they used to mount the glass to. http://www.ifixit.com/Teardown/iPad-2-Wi-Fi-Teardown/5071/1 Ive fitted laptop screens and a raw LCD panel has a thin steal bezel and back if you press the edge the light bleeds through EXACTLY like what we are seeing here! Apple has stuck on sponge sticky gasket on this then pushed it between the blackplate and digitiser in turn trapping the the panel tight in the device. Problem is the gasket causes pressure around the LCD panel as its to thick or dense in places and makes the backlight bleed! Apple SORT THE GASKET! and STOP giving me the wet glue excuse CRAP!! Anyone else think this?
